In the realm of server hardware, memory modules play a pivotal role in ensuring optimal performance and reliability. The HP 664691-001 8GB DDR3 ECC Registered Memory Module stands out as a critical component designed for specific server models such as DL360p, ML350p, BL460c, and BL660c. In this comprehensive guide, we'll delve into the intricacies of this memory module, exploring its specifications, features, compatibility, and benefits for server systems.

Overview of HP 664691-001 Memory Module

The HP 664691-001 is an 8GB DDR3 ECC Registered Memory Module, engineered to provide enhanced performance and stability in server environments. Its primary purpose is to augment the system memory of select HP server models, contributing to improved multitasking, data processing, and overall server efficiency.

1.2 DDR3 Technology and Its Significance

DDR3 (Double Data Rate 3) is a type of Synchronous Dynamic access memory (SDRAM) that offers higher data transfer rates and lower power consumption compared to its predecessors. This technology is crucial for modern servers, as it ensures faster access to stored information and supports the demanding workloads encountered in server environments.

Technical Specifications

The HP 664691-001 module boasts an 8GB capacity, providing a substantial boost to a server's memory resources. This capacity is particularly beneficial for handling resource-intensive applications, virtualization, and large datasets.

Memory Speed: 1600MHz

Operating at a speed of 1600MHz, this memory module ensures swift data transfer rates between the server's memory and the processor. The 1600MHz speed is indicative of the module's ability to handle data at a high frequency, contributing to responsive and efficient server performance.

CAS Latency (CL) and Its Role

The CL (Column Address Strobe Latency) of 11 signifies the time delay between the memory controller sending a command and the data being available for processing. A lower CL value indicates faster data retrieval and a CL of 11 ensures responsive performance in the HP 664691-001 module.

ECC (Error-Correcting Code) and Registered Design

Being ECC Registered, this memory module incorporates error-checking and correction capabilities, crucial for preventing and rectifying memory errors. The Registered design further enhances stability by buffering memory commands, making it suitable for mission-critical server applications where data integrity is paramount.

Single Rank Configuration

The HP 664691-001 module adopts a Single Rank configuration, which refers to the arrangement of memory chips on the module. Single Rank modules often provide better performance in specific applications, and their use is optimized for certain server architectures.

Compatible Server Models

The HP 664691-001 8GB DDR3 ECC Registered Memory Module is specifically designed for compatibility with select HP server models. Notable models include the DL360p, ML350p, BL460c, and BL660c. This targeted compatibility ensures seamless integration and optimal performance within these server environments.

Performance Benefits for DL360p, ML350p, BL460c, and BL660c

When integrated into compatible server models, this memory module contributes to enhanced performance in various ways. Increased memory capacity allows for more concurrent processes, improved multitasking capabilities, and better handling of memory-intensive applications. The ECC functionality ensures data integrity, reducing the risk of errors that could compromise system stability.


Ensuring the proper handling of the HP 664691-001 module is crucial to prevent electrostatic discharge and physical damage. Following the manufacturer's installation guidelines is imperative to guarantee a trouble-free and secure integration into the server system.

BIOS Configuration

After installation, it's essential to check and configure the server's BIOS settings to recognize and optimize the newly added memory module. This step ensures that the server fully utilizes the enhanced memory capacity and features provided by the HP 664691-001.

Advantages of HP 664691-001 Memory Module

The primary advantage of integrating the HP 664691-001 module is the substantial improvement in server performance. The increased memory capacity and higher data transfer rates contribute to faster data access and improved response times, especially in scenarios where large datasets or memory-intensive applications are prevalent.

Enhanced Multitasking Capabilities

With 8GB of additional memory, servers equipped with the HP 664691-001 module can seamlessly handle multiple tasks simultaneously. This is particularly beneficial in virtualized environments, where the server may need to support numerous virtual machines running diverse workloads.

Data Integrity and Reliability

The ECC and Registered features of this memory module play a pivotal role in ensuring data integrity and system reliability. By detecting and correcting errors in real time, the module helps prevent data corruption, making it suitable for critical applications where data accuracy is non-negotiable.

Optimal for Server Virtualization

Server virtualization environments, which involve running multiple virtual machines on a single physical server, benefit significantly from the enhanced capacity and performance provided by the HP 664691-001 module. This results in improved efficiency and resource utilization in virtualized infrastructures.
